The problem starts when the circuit board inside the fob comes in contact with water. It makes an excellent conductor, and it shorts out the components. It also accelerates the process of corrosion and rust.

This is a simple solution. Find something absorbent to place inside the fob. A tissue or paper towel would be ideal. Then apply the cotton swab, dipped in isopropyl alcohol and wipe down the circuit board and other components to clean out any battery acid residue or contamination. The fob should dry for a few days in a warm and dry environment.


Once the fob is dried out, replace the battery with a new one (of the same size and the same polarity ('+' with the upwards direction). The fob can be difficult to open to get to the battery, but should you have a flat-head screwdriver, it should be easy to slide in. After the fob is put back together, it should work in a normal manner. If it doesn't, you may need to reprogram it or replace the receiver module.

The Keylab

If a key-fob is functioning properly, it emits a radio frequency signal that is received by the module inside your car. If the signal is interrupted, your key fob won't function.

Some LED lighting from the aftermarket that utilizes the same frequency as the remote key fob may interfere with the signal and stop it from reaching the receiver modules. To prevent interference, the LED lights must be turned off, or to an alternative frequency.

If the issue continues to persist after replacing the battery, the antenna of your key fob may be damaged or not functioning properly. This is important since the antenna is responsible for sending an indication from the key fob to the receiver module. An OBDII scan will help diagnose the problem by revealing exactly what's wrong with the system. The scanner will ask you for details about the vehicle you own including the make and model, engine type, and VIN number.

Faulty Receiver Module

The key fob houses the receiver module which transmits the signals needed to lock and unlock. If this module fails then all the on-board electronics will cease to function. Reprogramming the keyfob using an OBDII scan or replacing it might help.

There are a variety of possible reasons for this problem which could be due to an empty coin battery, water damage, or signal interference. Try resetting the computer on board by disconnecting the battery 12 volts for 15 minutes. This will eliminate any remaining electricity that may cause issues. Begin by removing your cable from the negative terminal first, then the positive terminal. After 15 minutes, reconnect the battery in reverse order beginning with positive first, and negative second.

Dirt or water can harm the internal chip of the key fob. If your key's function stopped when it was wet, you need to clean the electronic component with isopropyl Alcohol or an electronics cleaner before reinstalling the battery. If your key has stopped working after exposure to salted or soapy water, it's likely that the chip is damaged and needs to be replaced.

Another possibility is an inoperable antenna module fuse that transmits the lock / unlock signal to the vehicle. Depending on the model, the fuse is located in a variety of locations like the engine bay, to the left of the dashboard, beneath the rear seat, or trunk.
